Cranial Nerves Cranial nerves are nerves of the PNS  that originate from or terminate in the  brain. There are 12 pairs of cranial  nerves, all of which pass through  foramina of the skull. Some cranial  nerves are sensory nerves (containing  only sensory fibers), some are motor  nerves (containing only motor fibers),  and some are mixed nerves (containing  a combination of sensory and motor  nerves). Characteristics of the cranial  nerves, which are numbered from  anterior to posterior as they attach to  the brain, are summarized in Table 1.
